Background of the issue:
I am trying to use ACF with fields set to 'Copy Once'. When viewing a page in English (Default Language) in the admin, I see the ACF Repeater Fields. However, when I toggle the language to Spanish, the ACF Repeater Fields are missing. This issue occurs on every page using ACF. Previously, I could edit fields in both English and Spanish. This issue does not occur on my dev site. I checked Screen Options, and it's not a visibility issue. Here is the link to the page where the issue can be seen: hidden link. Here is the link to the Spanish translation: hidden link.
Symptoms:
The ACF Repeater Fields do not appear in the admin when viewing pages in Spanish, preventing me from making edits. The product 'Maxfelt' was removed on the English site, but I cannot remove it on the Spanish site due to the missing ACF fields.
Questions:
Why are the ACF Repeater Fields missing in the admin for Spanish pages?
How can I ensure ACF fields appear for all languages in the admin?
